Experimental study on solids mixing and bubble behavior in a pseudo-2D, freely bubbling, gas-solid fluidized bed using PIV and DIA [PDF]

, 2007
The hydrodynamics of a freely bubbling, gas-solid fluidized bed has been investigated experimentally with non-invasive measuring techniques in a pseudo-2D column filled with glass beads of 400-600 μm fluidized with air.

Behavior of bubbles in large scale bubble column.

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1979
Experimental work was conducted with a 550 cm-diameter bubble column to find the influence of column diameter on circulating liquid flow, gas holdup, bubble size and bubble velocity. The relationship between average gas holdup and superficial gas velocity in the column is almost the same as that in a small-size bubble column.

Preliminary Study of a Ninj1‐Loaded Bimodal Ultrasound/NIR Fluorescence Targeted Molecular Probe for Diagnosing Early‐Stage Inflammation in Coronary Microvascular Dysfunction

Advanced Healthcare Materials, EarlyView.
Coronary microvascular dysfunction (CMD) targeting remains a challenge for precise diagnosis. This work presents a dual‐modal nanoprobe (T‐IR780‐NBs) that combines ultrasound contrast with near‐infrared fluorescence. This technology utilizes proteomics‐derived antibodies that specifically localize to inflamed and injured cardiac tissue, enabling ...

Molecular Design of Highly Efficient Heavy‐Atom‐Free Near‐Infrared Cyanine Photosensitizers for Fluorescence Image‐Guided Photodynamic Therapy of Solid Tumors

Advanced Healthcare Materials, EarlyView.
Highly efficient heavy‐atom‐free NIR photosensitizers based on a heptamethine cyanine platform were developed for image‐guided photodynamic therapy. Both in vitro and in vivo results revealed that the R820‐3 photosensitizer with a highly twisted molecular structure exhibited potential for NIR fluorescence image‐guided photodynamic cancer therapy ...
